Subject [jira] Resolved: (DIRSNICKERS-108) Wrong int encoding in Value

Emmanuel Lecharny resolved DIRSNICKERS-108:
-------------------------------------------

    Resolution: Fixed

Ok, with huge modifications, this problem has been fixed !

Basically, using previous BER code wrote for Snickers was much easier than trying to bringing
back from university all this binary theory I have forgotten ...

It drove me to modify the encoding and decoding of Integer, and had a side effect on Boolean
decoding.

Everything should be on track again...

Thanks Jérôme for the sharp reports, and for the time you dedicated on this f****g problem
!

btw, using BigInteger is not an option : it's 24x slower than doing it the way Snickers does
;)

WARNING : This is NOT compliant with ASN.1 BER, as the biggest ASN.1 BER integer is supposed
to be 256^126 - 1

> Hi,
> Encoding is buggy for int value in the org.apache.asn1new.ber.tlv.Value class. The affected
methods are :
> * public static int getNbBytes( int value )
> * public static byte[] getBytes( int value )
> Regards,
> Jérôme
